OKAY I'M SORRY. I PROMISE NO MORE NEW FIC UNTIL I FINISHED THE OTHER ONES BUT this is made due to popular request (okay, one or two request) and a really sweet private message that i really wanted to fulfil. It's just going to be a two parter, and writing this helps considering i'm still having some writer's block on the others.

This is a sequel of sorts to my other fic 'The Walls Are Too Thin', but you don'y have to read that first to make any sense of this one.

Oh and, you know how the first one's a bit humorous? Yeah, this one's not gonna be like that. It's a bit... angsty? i guess? but it's definitely explicit so, be warned.

But anyways! Hope you'd enjoy!

Whatever hesitation Ace might've felt the first time he invited Marco to come over his place melted down in a matter of minutes. It was mostly due to the fact that he knows for sure that Sabo and Luffy will not be around for days to come, and that once the door was closed, there's nothing stopping him from literally climbing all over Marco. This is his own territory, a familiar place where he did not have to worry about anything but the man holding him, far away from the possibility of someone seeing them interact for a moment too long and draw their conclusion.

Being in his own place, in his own house also gave Ace a better sense of security; it's a place of privacy, where no one can possibly hear them, but most importantly, it means that there's no urgency to check out or leave separately, which means Marco could stay longer and spend more time with him. There's a deep twinge in his chest, one that has nothing to do with the fact that the older male was now latching his mouth all over his chest and nipple. Ace wished he could say confidently that it was a sentiment shared between the two of them.

Maybe he should feel guilty for lying, but his excuse of 'my brothers aren't home' still contain some truth in them, and so does 'it's cheaper than a love hotel'. Because what else can he say? He knows Marco, knows that he'd feel guilty if Ace even mention the slightest that he wanted the man to stay and for once actually wake up together. He'd be fine if the guilt was out of agreement, but he had a strong feeling it'll only be out of sense of obligation, and that he can't handle. As much as Ace tried to pretend that this thing with Marco wasn't a casual meet up, he's never one to lie to himself.

He hated that he cared this much, but Ace knew he was doomed since the day he was first introduced to Marco on his very first day as a rookie in the district's precinct. Back then, he could only stare from afar, he could only imagine or talk Sabo's ears off about how amazing and gorgeous his mentor was, and honestly, if things had continued to be like that, maybe it'll be for the best. Because back then, he was sure that nothing would ever happen, and longingly wishing for someone's attention was a lot better than having only half of it and always craving more.

But that's not how things works in Ace's life. No, he had to wake up one day with the greatest hangover in his life next to the naked and sculpted body that he could recognize only by a glimpse of it. He had to face that fact that he couldn't remember the very first time he was deflowered - as Marco put it that very same day - by the man of his dream, but he could remember clearly that the first thing that came out of his mouth was 'i'm so sorry'. Ace's only consolation prize was that at least he managed to sleep with Marco, and that had been enough to make him smile to cover for the pang in his heart.

And yet, it didn't take long for them to fall into this routine, and the funny thing is, Ace was sure that this isn't what Marco had in mind. Marco didn't treat him any differently in front of others afterwards, but he corners him in quiet places, seeking apology and spewing an entire spiel about how he was responsible as Ace's commanding officer and he would understand if Ace reported him. Ace told him repeatedly that he wouldn't, and soft rebuke soon turned into aggression. He didn't need to know how much Marco regretted that night, he spat to the older, because Ace sure as hell didn't.

They fucked again that day in the basement file room, the corner-most area that hold cases dating back to 40 to 50 years ago and no one ever stepped a foot into. One minute, Ace had been pushing the older against the cabinet one minute, screaming at him to stop with the apologies and the next, he was straddling Marco's waist, riding him like he was a prized steed and Ace was an experienced jockey.

The memory of that day, as well as the consecutive events of their sneaking about made Ace shiver. Afterwards, it was like Marco had lost all sorts of restraint, and he took Ace to a whole new world, showed him things about himself he didn't even know. Fucking around in the precinct was getting too risky, especially after they were nearly caught in the upper level's lavatories, and bizarrely enough, it was after an arrest case that the idea of a hotel was introduced to the two of them.

It was 2 months in to these strange encounters when Ace began to realize that oh, he had set himself up as a fuck-buddy. Sure, Marco took him out for dinner every now and then, and once during their rare day off together, he even took him out of town, but every single one of those encounters ended up in a bed that wasn't their own. Their schedule was hectic and their individual lives more so, but the most frequent time Ace can see Marco aside from the station was in some discreetly placed 3 star hotel with dim lighting and bed with enough thread count and cleanliness that he at least won't end up with some disease of sorts.

And the worst thing is, Ace wanted more than just this, but he knew Marco didn't.

It's not hard to see. The first few times, they set up a rendezvous in some hourly hotel known for this sort of activity and once their time was up, Marco would drive him off to his own house, with one or two little quip about how he enjoyed that night. Seedy hotels turned to proper low budget hotels, one that made Ace question the dent it caused to Marco's wallet and when his offer to at least pay half of it was rejected, offered that maybe they can go back to his place instead. That was also rejected, because Marco didn't think Luffy or Sabo would appreciate that.

Marco's place was out of the equation, seeing that he shared them with the people they're trying to hide their entire 'relationship' from.

But that was when a new problem arise; Marco never had to drive him home again, but he was never there in the morning either.

In the span of minutes after closing the door, they were both in different states of undress. He wished that the new sense of privacy his apartment gave them, they could at least take their time a little bit, but as Marco more or less lifted him and disposed him to the nearest soft surface - the sofa - Ace mused that he didn't have that sort of patience. It had been a long stressful day in the precinct, with the amount of paperwork and transferal that needed to be done in before an impossible due date, as well as the anxiety that raised when he realized that Marco was called over to Pops' office more and more often lately. He tried to ask why once, but Marco had only brushed him off.

It was hard to think straight when Marco descended upon him like a striking wild beast, all powerful and feral, devouring him like he was a full course meal and he's hungrier than Luffy will ever be. He trailed kisses down from his lips to his neck, and Ace tried to stifle down his moan when Marco bit the juncture, quite close to his collarbone and one of his weak spot, while feeling his legs lifted by the back of his knees to circle around hard, sculpted waist, "Fuck," he cursed softly, one arm shooting out to grip on the sofa's hand rest and the other automatically burying itself to the tussled blonde locks that is Marco's hair.

He cursed again when the fabric of his cotton boxers brushed against his rapidly hardening cock, feeling the hard lump thrusting between his legs, "How are you so hard already?"

"I've gone half-mast since we stepped into this building and i've been ready since we walked in," he heard Marco growled against his heated skin, nipping all the way down from his collars to his abdomen, biting hard against the side of his ribs, "Need to have you now, it's been too fucking long. Bite you, eat you out, fucking bury myself in you so deep i'll never be able to pull out,"

Ace groaned out of arousal from Marco's words, but his mind worked differently. It scoffed at the implication, bitingly recalling the moments the man hightailed it once everything was over. The words itself never came out, at least, not in the way Ace's mind wanted it to sound like. With the hand still tangled in Marco's hair, he pulled the older up to eye level and leaned up to kiss him hard, pushing his tongue in and enjoying the access given to him inside of his superior's mouth, "Better put your money where your mouth is," the dark haired man purred once they separated, enjoying the sight of Marco's glazed eyes.

It didn't last long, unfortunately, or fortunately, when it was replaced by eyes burned with lust and passion, as rich as the voice caressing his ear, "I prefer putting my mouth all over your body,"

And who was Ace to stop that?

The concept of allowing Marco free reign over his body was nothing new, because Ace had long since learned that the man knows very well what he was doing. He simply goes along with the flow, giving encouragement through little moans and whimpers or an enthusiastic thrust and jolt, knowing that Marco loved seeing him like that. He shuddered with every lick to every crevice, sigh with every gentle kiss, and knows when the lift his hips up to allow himself to be stripped off from the last shred of clothing he had left. It was always a wonder to see how much he was leaking only by those little ministrations, as evident by the sight of his cock bouncing over his stomach once Marco roughly pulled his boxer away and toss them somewhere behind him.

"Fuck, touch me," he pleaded, wiggling his hips on Marco's lap a little as he held on tighter to the hand rest behind him.

But when Marco reach down, he barely did as he was asked. Ace whimpered at the gentle tracing of the blonde's finger over his pulsing arousal, stroking him only one time in an almost ghostlike fluttery touch, "Not gonna have you come from this," Marco whispered directly to his ear, and even without looking, Ace knew there's a smirk on his face. Behind squeezed close eyes, he could imagine them, the sharp upturn on Marco's thick lips, so frustrating to look at on a normal day and even more so when he started doing it in bed.

Hands roamed around his hips and down to his ass, cupping each mound with large, rough hands that came from years of field work. One of Marco's thumb - Ace was too dazed to figure out which one - starting prodding over his entrance, flicking over the puckered skin insistently, "Why don't you turn around, and let me touch you someplace else?" he whispered again, and Ace mewled when he felt the other thumb joining in the first, prodding and stretching around his hole.

Wordlessly, Ace turned - with some help, seeing that his legs were shaky and unable to stop - yet before he could even get into a comfortable position or even get a proper hold on to the hand rest, his hips was grabbed and pulled back. He yelped when he felt both of his legs being lifted up, his pelvic resting over strong shoulders and what was undeniably hot puffs of breath hitting his taint and the underside of his balls. Ace didn't need a mirror to know that the sudden heat rising over his head wasn't just from his blood rushing down, "Marco!"

Marco didn't answer, but instead, Ace could feel his tongue running up from his balls and to his entrance. When he squeak and muffled his moan, he felt Marco shaking slightly against him, obviously laughing. In embarrassment, Ace protested by swinging his forelegs in a round motion, ignoring the fact that he felt Marco's lips bumping against him even more, "Put me down! What the fuck are you— Aah!"

His grip on the hand rest nearly faltered when he suddenly felt his puckered muscles being shallowly penetrated by hot and wet tongue. One hand gripped the back of his thigh, close enough to the underneath of his rear, while the other was holding him up by his waist, a good solid grip which is a good thing because as Marco continued to lick and probe deeper, Ace began to trash about. He quivers the deeper Marco reached, knuckled gone white from how hard he was grasping the material and in reflex, he squeezed his thighs together, effectively trapping Marco's head in between them.

Not that Marco seems to mind; in fact, the hand on the back of his thigh moved to the side of it and actually pressed it closer against the older's cheek, and Ace could feel rather than see the smug smile than began to form on the older's face. Before he could protest, Marco's tongue disappeared from his hole, and not a second later it returned with what was unmistakably a finger along with it. The hand on his hips was gone, and the one pressing his thigh against the side of Marco's face tighten its grip and squeeze.

"Y-you have—uungh! You have no f-fucki-fucking shame," it was embarrassing how much he was reduced to a stuttering mess, feeling a stray drop of drool dripping out of the corner of his lips. Fuck, Marco's good at this, so much that even if Ace had been unwelcoming to this idea, it hadn't taken the older long to get him to get use to this. In fact, Ace was sure that he was long since conditioned for it, because he distinctly remembered that it hadn't felt this good the first time around, "I—Aah, there! There, please, again!"

But of course, the tongue stopped, retracting away with a mortifyingly loud and lewd 'pop', "I think i'm losing my touch. Can't be that good if you can still talk that much,"

"Fuck you, you know you are," Ace knew that Marco was only teasing, but at that point, he could care less if he's playing right into the older's hand. The finger brushing over his prostate had brought him closer to orgasm, and he need it now, "Marco, please,"

When Marco lightly bit the fleshy part of his rear, Ace could feel that he was smiling, his voice even smugger than before, "Now who have no shame? Begging like thi—" Ace didn't give him any time to finish, bending his legs by his knee to trap Marco's head from the back and squeezing them tight, shoving his waist back. From the surprised noise Marco gave, he's probably caught off guard by suddenly being smothered by ass and thighs. Hell, even Ace didn't know he could be that bendy or strong enough to support his body to do this, but he supposed arousal and the need to come are great motivators.

"You best put that mouth to work or so help me," the freckled male growled, ignoring how breathless and desperate he sounded.

That seems to be all Marco needed, because he chuckled, the motion making vibration down Ace's spine and gripped him so tight he's sure that his thighs will bruise everywhere tomorrow. Marco's tongue was accompanied by two fingers, probing deep where the hot muscle couldn't reach, and that was all that it took for Ace to go back to a whimpering, quivering mess. The rim of his hole felt sloppy, Marco's deft fingers immediately finding his spot with frightening accuracy and Ace knew he wouldn't last long. He's already leaking pre-cum as it is, and he's so damn close.

When Marco retracted his fingers, they came back in with a third, stretching him even further while still abusing his prostate, "Ye—ess!" the younger male moaned, stuttering, eyes squeeze shut, "Marco, oh— there! Please! Please, i'm so close—"

Ace came with an intelligible shout, shuddering at the spine-tingling hard press on the bundle of nerve inside of him and the light nip on his rim. His core burned from the burst of orgasm and without realizing it his hips stuttered, pressing him closer against Marco's face. The younger let himself flop down, arms too shaky to properly support him, not caring for the brief twinge on his spine due to the position until Marco slowly moved away and let his legs slide down to the sofa.

With a self-satisfied chuckle, Marco flipped him to his back, and realized his mistake a little too late. Ace's back made a squelching sound, which in turn made the raven groan amidst his panting, "Shit, you made me cum on the sofa," he groaned, his voice hitching in the middle, "Cleaning it's gonna be a pain, Sabo's going to kill me,"

Marco huffed, obviously unconcerned - because he's not the one who would have to deal with Sabo's ranting - and he moved over to loom over Ace's heaving and heated body, "We'll think of something," he said nonchalantly, "But that's for later,"

He leaned down for a kiss, and when he nearly bumped his nose to Ace's, the younger shot a hand up to cover his mouth, "Dude, you just had your mouth and tongue in my asshole. Are you seriously going to kiss me?"

A frown appear on Marco's visage, more annoyed than anything, "Ace, it's your ass,"

Ace considered this for a while, and shrugged, "Fair enough," and to make up for the obstruction he caused, he leaned up and caught Marco to a deep kiss. There's a taste there that he had never came across before whenever he kissed Marco, one that Ace quickly recognize as 'oh shit, that's me'. He could only describe it as weird, and not in a pleasant way, and he would've asked why Marco was always so insistent on doing it when he felt something hard poking on his thigh.

He tried to separate away and offer to take care of it to return the gesture, but Marco's started grinding against the same thigh, obviously aware of his own state. Ace wrapped both of his arms around the older's neck as he winded both of his slowly recovering legs around Marco's waist, rubbing against the still covered organ. Marco kissed him harder, one hand reaching up to hold the side of his head in place, grunting and moaning as he continued to thrust against Ace.

Soon, Marco separated away, albeit rather hesitantly, and hurried over to his pants just right in front of the table next to the sofa. He dug around his pocket like a crazed mad man, and when he pulled his hand out, Ace caught the sight of a silver foil wrapping.

And that made him burst out laughing because those pants hadn't been any normal pants, those are police uniforms and their division captain literally stashed away condoms inside of it without anyone realizing it, "Are you fucking serious?"

His humour was soon chased away like a frightened animal when Marco turned his heated gaze back at him, not even looking as he ripped the foil away with his mouth. He spat the ripped part away - yet another thing to clean - and fished the thankfully lubed condom, "Trust me," he said enigmatically, putting the condom on with the expertise that never fails to make Ace hot and bothered, "i'm always serious when it comes to fucking you,"

That had been Ace's only warning before Marco returned to his position over him, prodding his loosened entrance with the head of his cock. He sank down little by little, thrusting shallowly, letting Ace's sighs and hiss set his pace. By now everything was back to being familiar, a routine both knew each other enjoyed as much as they do, and in that brief moment, it cause Ace's stomach to flutter when he realized just how well Marco could read him, how in his obvious state of need, he was still attentive enough to make sure that Ace was good and comfortable.

It didn't take long for Marco to be sheathed in entirely, Ace's arms and legs back around his neck and waist respectively as the younger took deep breaths to brace himself, "You're doing a good job," he heard Marco muttered, trailing kisses down his cheek, "You're doing amazing, baby. You're so perfect around me, so hot, i'll make you feel good, gonna make you come again and fall apart in my hands,"

And it's not fair how much Ace liked hearing those words, the occasional sweetness that seeped out of Marco no matter how hard they're going, no matter what filthy things was said or done, before and after. It made it felt like for a moment there, this was sincere, that this wasn't what Ace now understand was just some fun romp in the sack and something to be hidden away from everyone else. That Marco never once said 'no one should ever find out about this', that their interaction wasn't just limited to random hotels and subtle glances at work, and that he never woke up alone, with only a piece of paper or a secretive whisper to remind him that the night before did happen.

Ace wished that he never figured out he was only Marco's dirty little secret, and he wished he was never okay with that.

The intrusion still stings, and he was far from being ready, but Ace thrusted his hips up and stifle his pained gasp when Marco moved because it made him stop thinking. He mewled and whimper as Marco began slowly, digging his nails down the older's back as the pressure increase, and soon the pain was quickly forgotten for the pleasure. Marco once again leaned down for a deep kiss, running his hand through Ace's now sweat damp hair.

Slowly but surely, Marco picked up his pace, his own impatience clear in his erratic thrusts. Ace lifted his hips higher and clung even tighter around Marco's waist, allowing a better angle, and they both began to moan and groan against each other's lips, a thin thread of saliva between them with the rest drooling out of the corner of Ace's mouth.

Somewhere on the background, Ace thought he heard a thump, but he couldn't be bothered to check. It could be that their motion was causing the sofa to bump against the wall, or it could be an angry neighbour who caught on with what they're doing, and both were inconsequential to him now. Marco drove one powerful thrust after another into him, and all Ace could do now was just stay in his mercy.

There's another thump again, and a noise that sounded too close like a person speaking, but in the same second as those thoughts cross his mind it also disappeared when Marco gave a particularly sharp thrust, "There! Oh god, there!" he screamed out in pure pleasure, which increase in volume as Marco angled himself again and thrusted directly towards that very same spot that made him see stars, "Fuck! Aangh! H-harder! Fuck me harder!"

Again, there's a squeak, almost sounding like someone was being choked, followed by what he was sure was a door slam, but it was so far away it may as well be from another unit or even another building. He had better things to think about, like the fact that in the middle of this pleasure, it all suddenly stopped, and without warning, he was lifted up to a sitting position, Marco's cock still inside of him and sliding even further due to the angle. It was already startling enough, and then Marco stood up.

"What are you— Ah!"

With a little stumbling, Ace found himself trapped between Marco and the wall just a feet away from the sofa, legs hanging in the air and Marco even deeper inside of him, all down to the base, "I always want to know how this feels like," Marco gasped out to his ear before thrusting up, and suddenly the stars were back in Ace's vision, "Fuck, am i regretting never doing this before,"

Honestly, as was Ace because Marco picked up where he left off immediately, and Ace shrieked. Aside from Marco's deep thrusting, gravity helped them greatly, and it took all of Ace's concentration not to topple off and held on to Marco while being assaulted over and over by mind-numbing sensation. His jaw felt sore by how much he was shouting and blubbering at that point, asking for nothing else but faster, harder, oh god it feels so good please don't stop.

Then, as if it wasn't enough, there's a stinging pain on his ass, causing Marco's thrust to stutter and Ace to let out a keening sound.

"You like that?" Marco's thrust was not as rapid as before, it was a lot more powerful, strong enough that Ace's breath was stolen out of him. Another swat to the underside of his ass, in tandem with a strong thrust and Ace could only sob and had his eyes rolling backward because it felt so good, it was so good it was slowly becoming too much. Marco chuckled, the sound strained by his effort to thrust, "Of course you do, how naughty,"

He thrusted again a couple of times, and when Ace least expected it, he spanked the underside of the younger's ass again, the fleshy side that made the loudest flesh to flesh slapping sound that sent shudder down Ace's spine, "Come on, say it," he commanded with another thrust, making Ace toss his head backward, "Do you like it?"

Marco thrusted up, maintaining the same intensity and slowly gaining his speed back, and at the same time bit the same spot on Ace's neck that made his knees weak and made his vision go white.

"Yes, yes, i like it! Oh god, yes! Spank me again, please—" his begging was cut short when Marco granted his wish, delivering painful slap one after another against his rear, all the while slamming into his prostate and biting on his sensitive spot.

Ace's second orgasm came like a freight train, hitting him with an intensity that had his entire body spasm against Marco's hold. He could barely register anything but his own high, only briefly shuddering when he felt hotness grew inside of him, and knew from Marco's gasp and strangled moan that he too had come.

Marco was panting hard, wincing even, but even so, he lowered Ace gently to the floor as he too slid down, both more or less kneeling down. For a moment, there was nothing but the sound of their laboured breath. Ace could feel his leg trembling underneath him, but Marco was worse off, hissing in pain as he pulled them up to cross them, "This is going to hurt tomorrow," he complained, yet when he lifted his head, he was tiredly smiling at Ace, "But it's so worth it,"

Ace snorted, but he couldn't really disagree. His back was sore now, the upper part from being repeatedly rubbed and slammed against the wall, and the lower an expected outcome. He felt sore everywhere, but Marco had a point; this was worth it.

After a brief moment, Marco stood up, glancing to the sofa and the myriad of clothing article thrown around it, and reality began to crash down to Ace's conscience.

Right, the sex's done, so they're done for the day. Marco's probably planning to leave, having no reason to stay longer. Things obviously wasn't going to play out as usual, with him falling asleep near immediately, and Marco slipping out afterwards, but as Marco made his way over to the sofa, Ace knew it'll hurt him more to actually see Marco physically leaving him behind.

Before he realized it and without even acknowledging the protesting pain on his backside, Ace stood up, and held on to Marco's hand.

"My bedroom's just right there," he gestured, leaning closer to the older man, "We can do this properly,"

Ace was already pretty exhausted, but he got Marco in his place now, he'd be damned if he'll let him leave.

Not just yet.

For a moment there, Ace waited in trepidation as Marco glanced again to the side, but there's a huge relief in his chest when the blonde smiled and nodded, "Well, the night's still young," he hummed, "Just let me take our clothes, wouldn't want to walk out tomorrow in the nude,"

"Why bother? It's not like there's anyone else,"

"Still, it's pretty messy since we're just tossing everything around,"

Rolling his eyes, Ace waited for Marco to finish gathering their strewn out clothes and led him into his bedroom. As Marco walked in, Ace gripped the door handle tightly before he closed the door behind him.

Maybe tonight, he can make Marco stay.

Next part's going to be Marco's POV, basically, and i hope i can have it done in a couple of days. Man, i love Christmas but i hate the work load that comes with it. Work's always gonna be there people, stop rushing to have it done before your vacation *mumble mumble* *rant rant*

...Anyway, thanks for reading and i hope you liked it!
